In subject area: Physics and Astronomy Big Bang Nucleosynthesis refers to the era in the early universe when nucleons combined to form light nuclei, such as deuterium, helium, and lithium, as the primordial plasma cooled down. This process depended on the rates of electromagnetic, weak, and st...

In subject area: Engineering Modern cosmology is based on the “big bang model,” according to which the universe is composed of particles which were mostly created in the aftermath of the explosion with which the universe began. From: Encyclopedia of Physical Science and Technology (Third Edition...
IGCSE Physics(0625&0972) 已从2023年开始将启用新大纲(2023-2025)。新增的天体部分,内容比较广泛,涉及了有关地月系、太阳系、恒星及宇宙的各个方面。带大家复习支持Big Bang Theory(宇宙大爆炸)的两大证据(Evidence)。这个知识点的考察考法可以很灵活,可以是选
The possibility that big‐bang nucleosynthesis (BBN) may produce nontrivial amounts of6Li is under study since the recent observations of this element in old halo stars. However, the interpretation of these observations needs a precise knowledge of the reaction rate of D(α, γ)6Li which, at...
